20	c --------------
21	c 21/06/01: Make integrations of more than one year possible ;-)
22	c ATTENTION!! runs are supposed to start with Jan, 1. 1930
23	c (rday=1)
24	c
25	c 27/06/01: Correction: The model always has 360 days per year!
26	c 27/06/01: SO4 concentration rather than mixing ratio
27	c 27/06/01: 10yr-mean-values to interpolate
28	c 20/08/01: Correct the error through integer-values in interpolations
29	c 21/08/01: Introduce flag to read in just one decade
